CARRYING MECHANISM;

Specification of Letters Patent. 1

Patented Sept. 23, 1913.

Application filed April 1912. Serial No. 699,732.

To all whom it may concern:

Be it known that I,- ARTHtm 'Han'rsorr, a citizen of the German Empire,and a resident of Linden, Hudson county, New Jersey, have inventedcertain new and useful I, Improvements in Carrying Mechanisms, of

my improved counting drum particularly tooth operating slide.

which the following is a specification.

This invention relates to improvements in carrying mechanisms forcalculating machines.

The object of the invention is to simplify the construction and designof certain parts or elements of the carrying mechanism and to providemeans for a better and more positive operation than is possible withother constructions known to the art.

in the drawings illustrating my invention and accompanying thisspecification l igure 1 is a partial plan view of a calculating machineillustrating my invention, Fig. 2 is a side elevation of the parts'shownin Fig 1. Fig.3 a transverse sectional view. F 4:, 5, 6 and 7 are detailviews of illustrating the movable tooth carried thereon. F 1g. 8illustrates a certain oscillating circular lever for operating themovable tootln Fig. 9 illustrates in detail the mov-,

able tooth. Fig. 10 illustrates in detail the cover plate for the tooth.Fig. 11 shows the Fig. 12 shows the tooth operating lever and cam. Fig.13 illustrates steps in the operation of my de vice. Fig. 14 is a detailview of the locking lever. Fig. 15 is an enlarged view of thecounting-diaun and its associated parts ineluding the movable tooth andFig. 16 is a plan view showing how the movable tooth' -is supported andoperated on a toothless with nine teeth.

counting drum.

. Referring to Figs. 1, 2 and 3 the numeral 1 represents the frameworkin which the counting drums 2, 2 are journaled in known manncrz- Ilachdrum is as usual provided 3, 3, are the tens wheels slidably supportedon the "quare shafts t which also carry the locking wheels 5 whichcooperate with the locking cams G of the counting drums.

7, '7 are the usual number wheels each of" which 1s 1".!'()'\'ltl0(lwlth the carrying arm 8.

9 is the counting drum operating shaftwhich is rotated from the shaft 10in the usual manner by a handle, not shown. I

()no object of my invention is to provide a more positive drive of thecounting drums from the shaft 9 than is possible by means .of individualgearing. To this end I drive only the two end shafts 11, 11 by gears 12,

12 from the driving shaft 9-, and on the innerend ,of each counting-drumshaft 11 I mount a crank 13, and all of the latter are connected by asin l'e connectin rod 14. By this means all tIi operated positively atone and the same time and'I dispense with a great many gears whichotherwise would be needed for this purpose. The positive drivingconnection between the counting drums prevents all lost motion 'andisvery advantageous and simple to build.

Another object of my invention is to eliminate the separate tenstransferring tooth as an independent se arate element mounted andoperated away rom the count e counting rums are ing drums, whichnecessitates a complicated for the tens transferring means. a

In this instance I mount the tens transferring tooth directly onthecounting drums as a'movable tooth thereon and provide a suitableoperating mechanismtherefor.

Referring to the Figs. 4 to 15 it will be seen that the counting drum '2iscut out to form sockets 15, 15 in which are secured pins 16,16, Fig.5. On the latter are pivoted circular swinging'levers 17, 17.- Eachlever hasan aperture 18 to fit over its pin 16, Fig. S,'and carries twopins 19 and 20. The. pins 20 enter. apertures 21 in the movable tooth 22Fig. 9, to operate said tooth, and the pins 19 enter apertures 23 intheslide 24-1 Fig. 11. The slide has stops 25 which enter into andcooperate with thecut out portions 26 in the tooth. The slide carries. apin 27. 28 is a cover plate which is fastened to the. counting drum by ascrew 29, F ig. 4.

and which also has an opening 30, Fig. 10.

31 is a lever with a notched end 32-, Fig. 12, adapted to enter throughthe opening 30 in the cover plate and receive the pin 27 of the slide asshown in Fig. 7.

Figs. 5 and 6 show clearly the operation of the movable or tenstransferring tooth. It will be seen that in Fig. 5 the tooth is ininactive'position below the periphery of the counting drum. In Fig. 6the slide 24 is at the extreme right, having been brou ht into thisposition by the lever 31 engaging toothless drums 34 and acorrespondingly tooth to the right and radially outwardflto project the,tooth beyond the periphery. of

the countingdrum and into active position. The tooth is provided with aslot 33 which fits over the screw 29 aforesaid. The lever 31 is guidedon the drum-in a cut out portion as-at 60 in the locking cam 6.

The stops 25 and cut out portions 26 co operate to guide the movement ofthe tooth. Each counting drum except the first onethe .one to the rightin Fig. 1-is provided with a tens transferring tooth. The shafts 11 tothe left are provided with very short short tooth 35 operated by meansof a single swinging lever 67 pivoted on the drum 34 in a socket 65 inthe same manner in which the levers 17 are pivoted on the drums 2. Thelever 61 extending from the collars 68 actuates the lever 65 which, bybeing oscillated, projects the tooth 35 radially outward fromthe drum.The tooth s carried in a socket in the drum and it and the lever 67 areprevented from displacement by a cover plate 7 8 similar to cover plates28 aforesaid. '79 is an abutment on drum 34 against which the tooth 35slides. When the short tooth 35 is moved into active position it engagesat the proper time the gear 36 to operate the last number wheel in aknown manner. 1 a

The lever 31 is provided with a hub 37 and a collar 38 having a cam39.The lever 31 is reciprocated on the counting drum by the followingmeans.

On the frame is suitably pivoted at 40 a carrying lever 41 which has alug 42 which engages the collar 38 and which also carries a roller 43adapted to cooperate with an oscillating arm 44, pivoted at 45. When,during the operation of the machine, the

' tens wheel has been engaged by the counting drum and the correspondingnumber wheel registers'naught, the carrying arm 8 strikes the arm 44which throws the roller 43 inward and oscillates the carrying lever 41.Consequently the collar 38 or 68 in Fig. 16 is moved to the right inFig. 7 and the tens transferring tooth is projected into active positionto engage the next or adjacent tens wheel which in turn operates thenext number wheel and so on as is known.

In order to prevent an incomplete operation I provide means forpositively 'holding the lever 31 in its retracted position when the samehas been operated by the carrying lever 41.

Referring to Figs. 3, 13' and 14 the numeral 47 represents a lockinghook pivoted at and suitably secured to the frame. A spring 49, onlyshown in Fig. 14,tends to keep the hook horizontally. The collar 38 iscut out as at 50. Normally the hook and collar are in the position shownat the top in Fig-13, that is, the hook is in engagement with the collarbut the cut out portion 50 is opposite the hook. Consequently,

the collar is free to move axially on the counting drum shaft 11 whenactuated by the carrying lever 41. The axial and at the same time rotarymovement of the collar 38 forces the hook aside as shown in the secondposition in Fig. 13 and immediately thereafter the collar completes itsaxial movement and the hook snaps over said collar and locks it as shownat the bottom of Fig. 3, that is during the tens transfera ringmovement, thus absolutelylocking the collar against accidental returnmovement, an occurrence which is apt to happen with a less positivelocking device. When, however, the arm 44 moves back into normalposition,-the cam 39 again moves the collar 38 to the left in Fig. 3,which it can do by that time the cut out portion 50 is again oppositethe hook and the collar'can pass the latter. .The hook new again engagesthe collar to lock the same. I Y

It will be seen that first, I have provided a positive drive for thecounting drums. Second, the tens transferring tooth is placed directlyon said drum, a feature which I believe. to be broadly new, and a verysimple carrying nlechanism is provided in the space between two countingdrums. Finally a positive locking device is provided to insure theactive position of the tens transferring tooth.

I do not wish to be restricted to the exact details shown or describedexcept as. the appended claims demand.
